Title: Damper device
Inventor: OYAMA MAKOTO
IPC: A47B51/00
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To vary the operating characteristics by changing the area of an orifice in accordance with the load applied, simplify the configuration, and generate stabilized damper characteristics. SOLUTION: A resilient body 11 is furnished with an orifice 12 through which a working fluid 4 flows in association with movement of a piston 2, and a part 10 for mounting of the resilient body 11 is formed on the piston 2. The shape and section area of the resilient body 11 and orifice 12 vary in accordance with the force applied to the piston 2, and it is possible to change the damper characteristics themselves in accordance with the force applied. The resilient body mounting part 10 provided on the piston 2 eliminates necessity for use of any complicated configuration such as double cylinder structure to lead to simplification of the whole damper device construction.

Title: Method and device for generating template for signature collation and signature collating device
Inventor: OBATA KENZO
IPC: G06K9/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To make the part where individual features of a signature registerer are reflected most settable as feature points of a registered signature when a template for sign collation by fuzzy inference is generated from the feature points of the registered signature. SOLUTION: A gene operation part 14 extracts the partial curve where individual features of a registerer are reflected most from signatures that the registerer has written according to locally improved type generic algorithm, and a template generation part 16 generates a membership function for fuzzily inferring matching degrees for every partial curve to generate a template for sign collation. A gene locus specifying a partial curve consists of the stroke number that the partial curve belongs to and information showing the start point and end point of the partial curve on the stroke. Consequently, a signature collation part 22 while securing the precision at the time of signature collation can reduce the amount of data of the template.

IPC: B24B19/02
Filed: 1992-12-01
Abstract: PURPOSE: To cut a groove on the surface of a wet concrete. CONSTITUTION: A concrete saw 20 comprises a motor driven rotating cutting blade 46 mounted on a support structure. The concrete saw is supported during cutting by wheels, and has a skid plate 42 with a slot through which the rotating cutting blade passes to cut the concrete. The plate is movably attached to the concrete saw and resiliently urged against the concrete during cutting so that it remains in contact with the surface of the concrete surrounding the cutting blade during cutting. The skid plate is constrained into a bowed configuration so that it is substantially flat during cutting. A variable speed transmission is drivingly connected to wheels 48 to propel the saw across the concrete during cutting.  A sensor detects the relative position of the skid plate and the cutting blade to generate an electric signal which cooperates with the variable speed transmission to slow down the saw as it encounters hard aggregate, and to speed up the saw as it encounters soft concrete.

Title: Light separation prism
Inventor: MONMA SATORU
IPC: G02B5/04
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of refractive index, the occurrence of problem on transmittance, the increase of the rate of rejects and the rise of cost by using high purity quartz as the material of prism pieces. SOLUTION: The inclined planes of right-angled triangular prism-shaped quartz pieces 21, 22 comprising high purity synthetic quartz are joined to each other by way of a wavelength separation film 23 to obtain the objective light separation prism 20. Since the prism 20 is a cube, the angle 0 θ of the wavelength separation film 23 is 45 deg.. Since the wavelength separation film 23 is formed along a diagonal plane of impurity-free cubic synthetic quartz (SiO2), the refractive index of the quartz part of the prism 20 is 1.44 which is lower than the refractive index (1.55) of impurity-containing BK glass. Even if the wavelength separation film 23 has unevenness in density due to a production error, the light separation performance of the prism 20 is hardly affected and the prism 20 is used as a good product.

Abstract: PURPOSE:To execute stable musical sound control by utilizing the movement of a human body at the time of dancing, etc., by comparing the movement detecting signal of part of the human body with high and low reference values and starting to output musical sound control signals when the movement detect signal exceeds the higher reference signal and a stopping the output when the movement detecting signal becomes lower than the lower reference signal. CONSTITUTION:A movement sensor 10 which detects the movement of part of a human body (movement of a finger) is provided. The sensor 10 is constituted of a variable resistor and outputs a voltage signal Sa by detecting the expansion and contraction of a finger. The output of the sensor 10 is connected to the positive-side input of a comparator 21 and negative-side input of another comparator 22 and a high-level and low-level reference voltages are respectively connected with the facing input terminals of the comparators 21 and 22. When the signal Sa exceeds the high-level reference voltage at the comparator 21, the comparator 21 outputs a signal of an 'H' level to the S-terminal of a flip flop circuit. As a result, a 'Key ON' signal KON is outputted and control of musical sounds is started. When an 'H' level signal arrives from the comparator 22, the signal KON is stopped. Even when the movement of the finger vibrates to some extent, the musical sound control signal is not moved and stably generated.
